chords of resonance for a glass bottle harmonica

To create a glass bottle harmonica, you will need several glass bottles of varying sizes, each filled with a different amount of water. When you blow across the openings of the bottles, it will produce different musical tones based on the bottle's size and the amount of water inside it.

Here are some common chords of resonance you can create on a glass bottle harmonica:

1. C Major Chord:
- Bottles: C, E, G
- Water levels: C bottle half-filled, E bottle 1/4 filled, G bottle 1/8 filled

2. D Major Chord:
- Bottles: D, F#, A
- Water levels: D bottle half-filled, F# bottle 1/4 filled, A bottle 1/8 filled

3. E Major Chord:

- Water levels: E bottle half-filled, G# bottle 1/4 filled, B bottle 1/8 filled

4. F Major Chord:
